Variability in seed yield of castor genotypes and its association between different yield contributing traits as well as genetic advance were studied during kharif-2012 with 23 CRIDA castor genotypes under rain-fed conditions in alfisols. Superior genotypes for yield and its components were identified. The variability for genotypes was significant for seed yield and all its four components studied viz., number of branches, number of nodes, capsule number and capsule weight. The correlation coefficient analysis revealed that seed yield was highly significantly correlated with capsule number and capsule weight. High heritability with high genetic advance as mean (GAM) was observed for capsule number, capsule weight and seed yield, there by revealing that selection for high capsule number and capsule weight will increase the seed yield in castor. Based on the seed yield performance, twelve genotypes which yielded above 63.57g/pl (average yield of 23 genotypes) were selected for further evaluation of physiological efficiency coupled with seed yield. It was observed that CRC-4 is the only genotype where in the range for five characters was 2-6 ranks, thereby revealing that this is a desirable genotype with higher ranks for all the five characters studied.
